Question:
A declining Industrial Town has proposed to improve water sustainability by reducing stormwater runoff through change of land use land cover (LULC), as shown in the Table below, to attract new residents.
LULC Runoff Coefficient Existing Area in hectare Proposed Area in hectare Industrial 0.7 1500 800 Residential 0.5 1000 1200 Park and Playgrounds 0.25 1200 1000 Forest 0.15 300 1000
Considering a flat topography and zero additional runoff from the adjoining areas, the reduction in run-off generation for a 400 mm rainfall event in the industrial town for the proposed intervention, in cubic meters, is _____ \(\times 10^6\) (rounded off to two decimal places).

Top Questions on Water harvesting systems
- The annual precipitation recorded in a town is 400 mm. Rainwater is being collected from the flat roof of a building, and then treated to potable standards, and stored. Water loss due to evaporation, transmission and treatment is 40 percent of the total harvested volume. The roof area is 500 sq.m. There are 3 occupants, with average daily water demand as 200 lpcd. The stored rainwater will be adequate for the household's daily use for \underline{\hspace{1cm}} days [in integer].
